Well, since even Captain "Tightpants" from Firefly probably can no longer FIT in those "tight pants"... I would say that these men and women have the same temptations / failings as the rest of the country.

Well, Beltran was hefty for a number of years, but he's seriously dropped the weight per these pics. In a recent pic i saw with Ethan and Garrett, Beltran's belt was taken in a few notches. Looks like he needs to buy "thin" clothes that fit him just a bit better. He looks great!
